我想发送一个简单的POST命令来上传文件。如何在android开发人员中编写代码？代码应该提供以下POST请求

POST /macros/s/AqtUErjtk/postform?no&func=uploadFiles HTTP/1.1

在以下链接中，您将看到一个POST的示例：

https://community.particle.io/t/example-android-application-post-get/9355

这是从上面的链接中提取的确切代码：

class PostClient extends AsyncTask<String, Void, String> {
        public String doInBackground(String... IO) {

            // Predefine variables
            String io = new String(IO[0]);
            URL url;

            try {
                // Stuff variables
                url = new URL("https://api.spark.io/v1/devices/YOURCOREID/SCL/");
                String param = "access_token=YOURACCESSTOKEN&params=d7,"+io;
                Log.d(TAG, "param:" + param);

                // Open a connection using HttpURLConnection
                HttpsURLConnection con = (HttpsURLConnection) url.openConnection();

                con.setReadTimeout(7000);
                con.setConnectTimeout(7000);
                con.setDoOutput(true);
                con.setDoInput(true);
                con.setInstanceFollowRedirects(false);
                con.setRequestMethod("POST");
                con.setFixedLengthStreamingMode(param.getBytes().length);
                con.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");

                // Send
                PrintWriter out = new PrintWriter(con.getOutputStream());
                out.print(param);
                out.close();

                con.connect();

                BufferedReader in = null;
                if (con.getResponseCode() != 200) {
                    in = new BufferedReader(new InputStreamReader(con.getErrorStream()));
                    Log.d(TAG, "!=200: " + in);
                } else {
                    in = new BufferedReader(new InputStreamReader(con.getInputStream()));
                    Log.d(TAG, "POST request send successful: " + in);
                };


            } catch (Exception e) {
                Log.d(TAG, "Exception");
                e.printStackTrace();
                return null;
            }
            // Set null and we´e good to go
            return null;
        }
    }
}

我希望它有所帮助。
